Answer:
Chlorophyll
Explanation:
because they lack roots, stems, and leaves.
2. To transport water to the entire plant, especially the leaves where photosynthesis takes place. This is important because water is required for photosynthesis to take place.
3. Chlorophyll.
4. The palisade layer contains the most chloroplasts.
5. The function of the stomata is to allow gas exchange to facilitate photosynthesis. It also controls the rate of photosynthesis to regulate water use of the plant. Without it, plant would have severely hindered transpiration, causing the plant to die.
6. Chloroplasts are where photosynthesis takes place. Without chloroplasts, no synthesis would happen.
7. A leaf from a desert plant would likely have less stomata to conserve water content in the plant from evaporation due to environmental factors. This is because water escapes to the environment when stomata are open in plants. The contrary would be the case for plants in a tropical environment where water is more abundant and sunlight is more lacking.
Some common elements that are gaseous state at room temperature are:
Oxygen
Nitorgen
Fluorine
Chlorine
Hydrogen
Helium
In addition, all of the elements in group VIII are gases too, they have an octet of electrons (complete outer electron shell) , they're really stable and therefore they're called noble gases. Some examples from group VIII include helium, krypton, xenon etc.
Substance exist as gases in room temperature is due to their boiling point, where is it lower than the room temperature (usually around 25°C). If their boiling point is higher than room temperature, they should exist as either solid or liquid, which is how the majority of the elements in the periodic table is.
Answer: browning
Explanation: a healed cut will have brown around it, a fresh cut will not have brown
